Specification of Letters Patent.

Patented May 7, 1912.

Application filed November 17, 1910. Serial No. 592,863.

To all whom it may concern:

Be it known that I, JEssE DUNrEE, a citizen of the United States,residing at Coshocton, in the county of Coshocton and State of Ohio,have invented certain new and useful Improvements in lVrappers, of whichthe following is a specification.

This invention relates to wrappers for fragile articles and moreparticularly to an improved method of forming the same.

The object of the invention is to produce a wrapper which, whenpositioned in quantitles in proximity to one another, will notinter-fit, but will be held apart so as to provide an eflicientprotector for the article housed thereby.

The method consists in forming a hollow wrapper with diagonalcorrugations or crimps in the sides thereof so that when two or more ofthe wrappers are brought together, the corrugations or crimps thereofwill intersect and thus be prevented from intermeshing.

The method further consists in folding a blank and crimping the foldedblank to form corrugations in the plies thereof extending at an angle tothe edge of the adjacent fold.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing in which Figure 1 is aplan view of the blank from which the wrapper is formed. Fig. 2 is aView of the blank when curved into cylindrical form. Fig. 3 is a view ofthe blank flattened. Fig. 4 is a view of the same'when folded. Fig. 5discloses the manner in which the blank is passed through the corrugatedrollers. Fig. 6 is a perspective view of the complete wrapper. Fig. 7 isa similar view disclosing a bottle as applied to the same.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

Referring to the drawing the numeral 10 designates a blank which isformed from strawboard, paper, cardboard, or the like, and whichis'rectangular in form as is disclosed to advantage in Fig. 1. The blank10 is rolled into cylindrical form, as is disclosed in Fig. 2, havingthe free ends thereof overlapped as at 11. The overlapping ends 11 areheld together by an adhesive substance, or the like.

In forming the wrapper from the blank,"

after the blank has been rolled into'a cylinder, as is disclosed in Fig.2, the blank is fiat-toned, as shown in Fig. 3, when it is doubled orfolded upon itself longitudinally as shown in Fig. 4:. When the blank isfolded as disclosed in Fig. 4 it forms four thicknesses or plies 10,10", 10 and 10, which are superimposed and constitute the sides of thewrapper when completed.

In Fig. 5 is disclosed a pair of c0rrugating rollers 12 which are flutedlongitudinally and arranged to intermesh. The blank, when folded toprovide four thicknesses or plies as is disclosed in Fig. 4, is passedbetween the rollers 12 at an angle of from thirty to sixty degrees tothe longitudinal axis of the rollers so as to provide a series ofdiagonal corrugations in the four sides of the wrapper. After the blankhas passed through thecorrugated rollers 12 it is unfolded to assume thecylindrical form which is disclosed in Fig. 6. It will be noted that theplies 10 and 10 have corrugations running at substantially oppositeangles and that the corrugations meet at the common marginal edge orline'of fold of the sides.

In a like manner it will be noted that the plies 10 and 10.arecorrugated oppositely and have their corrugations running in an oppositedirection to their respective adjacent plies 10 and 10.

From Fig. 7 it will be observed that the improved wrapper 10 isPositioned about the fragile article, such as a bottle 13, in the usualmanner. It will be noted that in this method of forming the wrapper thatit is necessary to pass the blank between the corrugating rollers 12 butonce to effect the crimping of the four sides of the wrapper and todispose the corrugations thereof in opposite angles.

By providing a wrapper with a number of sides having corrugations lyingin diiferent angles to one another, the wrapper when disclosed between anumber of like wrappers, can be easily placed to dispose thecorrugations of the adjacent wrappers in cross relation so as not tointermesh. By forming the wrapper with a number of the faces which areoppositely corrugated it is necessary but to turn the wrapper through aslight angle to dispose the adjacent corrugations in crossed relation.

-Having thus described the invention What is claimed as new is:-

1. The method of forming hollow corrugated Wrappers, which consists infolding a blank to produce a plurality of superposed plies all of thesame width, and crimping the folded blank to form oppositely inclinedcorrugations in the plies thereof intersecting at the folds in saidblank.

2. The method of forming hollow corrugated wrappers, which consists infolding a blank to form a plurality of superposed plies of equal widthand overlapping each other for the entire distance between the folds inthe blank, and crimping the folded blank to produceoppositely inclinedcorrugations extending the entire width of the several plies, with thecorrugations of the plies intersecting at the folds in the blank.

3. The method of forming hollow corrugated wrappers, which consists infolding a blank to produce a plurality of overlapping superposed pliesof equal width, and passing the folded blank between corrugated rollerswith one longitudinal edge of the blank arranged at an angle to thelength of the corrugations on the rollers to produce oppositely inclinedcorrugations in the different plies, extending the entire width thereofandintersecting at the adjacent folds in said blank.

4. The method of forming hollow c0rrugated wrappers, which consists infolding a blank to produce a plurality of superposed overlapping pliesall of the same width, introducing one corner of the folded'blank bctween a pair of corrugated rollers, and subsequently passing the entireblank between said rollers to form oppositely inclined corrugations inthe dilferent plies extending the entire width thereof, and intersectingat the junction of said plies.

5. The method of forming hollow corrugated wrappers, which consists infolding a blank upon itself and then doubling the blank to form fourplies of equal width, and finally passing the doubled blank obliquelybetween crimping rollers to form oppositely inclined corrugations in thedifferent plies of the blank, with the corrugations in one plyintersecting the corrugations of an adjacent ply at the junctionthereof.

6. The method of forming hollow corrugated wrappers, which consists intaking a flat blank and bending the same to form a tubular body,flattening the tubular body to produce two plies, doubling thc'flattened blank upon itself to produce four plies, passingone corner ofthe folded blank between a pair of corrugated rollers, and subsequently, passing the entire blank between said rollers to formoppositely inclined corrugations on the different plies of said blank.

In testimony whereof, I atlix my signature in presence of two witnesses.
